We have a guy in an essilor lens with an essilor AR with an essilor photochromic in polycarbonate. Twice, now, separated by about a year, his Transitions Gray lenses have increasing residual color in the unactivated state. Strangely, it looks brown-yellowish, is about 15-20% density, and it's distributed according to the mass of the lens, i.e. he's -4.50 and it's darker at the edges than the center, like an in-mass tint.
Anyone have any ideas why this guy would keep doing whatever it is he's doing, and what the issue is? He does admit to being outdoors a lot.
